Abstract: VIDEO DISPLAY MOUNTING MECHANISM PROVIDING PIVOTING     AND TILTING OF THE DISPLAY          Abstract of the Disclosure A mechanism for mounting a video display unit (or the like) to a base unit is disclosed.  The mechanism includes a ball-shaped (or partial sphere-shaped) portion which mounts to the bottom of the display unit.  The base carries a circular bevelled rim-shaped member for mating with, and providing support for, the ball-shaped member.  A slot in the ball-shaped member carries a sliding member.  A stud, fixed to the base unit, passes through the sliding member such that pivoting of the display unit occurs about the axis of the stud.  Tilting occurs by the display unit moving relative to the sliding member (i.e. the sliding member moves in the slot).  Consequently, tilting is provided about an axis orthogonal to the axis of the stud.     - i -

Abstract: INVENTOR: ROGER MICHAUD     TITLE:    FURNACE HEAT EXCHANGER     ABSTRACT OF THE DISCLOSURE        A heat recovery system recovers heat from flue gases from a furnace or the like and a hot water cylinder. Flue gases are passed through series of chambers in which coils are located.  Water is passed through the coils in a direction opposite to flue gas flow to maximise heat transfer and the heated water is passed to either a heat radiating system or into preheater tank for the hot water supply.  The coils for the heat radiation and water heating are in separate circuits and the flue gases from the  hot water is passed only over the coil used for water heating.  Pumps are used for water recirculation in both the heat radiating circuit and the water heating circuit.  The system has application to domestic and industrial furnaces which provide gaseous combustion products with recoverable thermal energy and permits the use of a small diameter exhaust vent without adversely affecting the ignition and combustion system of conventional furnaces.

Abstract: TIMING SIGNAL CORRECTION SYSTEM FOR USE IN DIRECT SEQUENCE  SPREAD SPECTRUM SIGNAL RECEIVER                            Abstract A direct sequence spread spectrum transmitter and receiver can be synchronized when the timing reference frequency is less than or equal to the data sampling rate and the ratio of the data sampling rate to the timing reference is an integer by combining two,  four or eight consecutive data samples  to yield one data sample point.  By combining these data samples,  an optimum data sample point may be determined while receiving an alternating sign preamble by comparing the magnitudes of all possible summations and selecting the sample which gives a maximum output. If each sample  is  assigned  to  its  own  synchronization  point,  then synchronization may be accomplished by locking to the time that gives the maximum output.

Abstract: ABSTRACT     There is described a transmitting data processing sys-tem used in a node of a data transmitting system, like a local area network, which uses a relatively long ranged transmission line and a large number of nodes on the transmission line for relaying a frame comprising a preamble pattern and transmitting data.  A beginning part of the preamble pattern is dissipated in the node when a clock signal is extracted from the preamble pattern.  The dissipated part is restored in the node by adding a newly generated preamble signal having a time duration sub-stantially equal to the time duration of the dissipated part at the head of the dissipated preamble pattern after sensing the dissipated preamble pattern.  Alternatively, the dissipated preamble pattern is replaced with a newly generated preamble pattern which is equal to a standard preamble pattern after sensing a carrier of the frame.  The invention permits trans-mission through a large number of nodes without the necessity of a long preamble pattern.
